As an Staff Advanced Mission Concepts Engineer at Impulse, you will bridge the gap between high-level customer ambitions and the hard-engineering reality of our orbital transfer vehicles. You will own the physics-based feasibility of our future missions, ensuring we don't just "bid" missions, but architect them for success. You will sit within the Mission Management team, partnering with Business Development and Engineering to shape mission concepts, define system-level requirements, and ensure every solution is physically executable. This role includes direct customer engagement and occasional travel.
